Portion AI - I got tired of 9.99/mo AI calorie trackers, so I built one for 2.99/mo

Hey r/SideProject . Solo dev here, and I just launched my first iOS app. Every AI calorie tracker I looked at converged on $9.99 a month or more, which felt steep for an app that reads a photo of your lunch. So I built Portion AI: snap a photo of your food, or just type "two eggs and toast", and the AI logs the meal with macros. The thing I actually like best is the text logging. Every competitor is photo-first, which means staging a photo of every meal. Typing what you ate is faster for

AI 分析

痛点:主流 AI 卡路里记录 App 普遍定价 $9.99/月偏贵,且几乎全是「先拍照」的交互,记录每餐都要摆拍,日常使用太麻烦。

目标用户:需要长期记录饮食的减脂/健身人群,尤其是嫌 $9.99/月太贵、又懒得每餐拍照的轻度用户。

证据:Every AI calorie tracker I looked at converged on $9.99 a month or more, which felt steep for an app that reads a photo of your lunch. ... Every competitor is photo-first, which means staging a photo of every meal. Typing what you ate is faster for real life ... It's $2.99/mo with a 7-day free trial (deliberately way under the $9.99 standard).

变现:低价订阅制($2.99/月或 ~$19.99/年)+ 7 天免费试用,用 RevenueCat/StoreKit 做订阅墙;可加一次性买断选项或按年折扣提高 LTV。

MVP:2 周可做:iOS 单页 App,输入框支持自然语言("two eggs and toast")+ 相册/相机调用多模态 LLM 解析食物与宏量营养素,本地历史记录 + 每日热量/蛋白进度环,接 RevenueCat 上 $2.99/月订阅墙;先用现成 API(OpenAI/Gemini)不训练模型。

竞品:MyFitnessPal、Cal AI、MacroFactor、SnapCalorie、Lose It!、Cronometer、Foodvisor

摘要:一名独立开发者因不满市面上 AI 卡路里记录 App 普遍 $9.99/月,自己做了 Portion AI,定价 $2.99/月并主打「文字输入优先、拍照为辅」的记录方式,9 月已上架 App Store。帖子里有明确的竞品价格锚点和大厂定价验证,但作者未披露任何下载量、收入或用户反馈数据。该赛道竞品极多且同质化严重,低价切入是可行差异点,但竞争空间有限。
